    Default UEFI or Legacy?

    Hi

    I hope that I am not repeating a similar question.

    Let's assume that:
    1) I can disable secure boot.
    2) I accept the default "Suggested Partitioning" of the network installer.
    3) I choose the user Interface "Desktop with KDE Plasma" of the network installer.
    4) I accept the default "Installer Settings" of the network installer.

    If I install openSUSE on the entire HDD, should I choose UEFI or Legacy?

    Thanks in advance!

    As your system is bought, it is either UEFI or not. Stick to what it is.

    I am sorry, but I don't understand...
    My laptop is https://snlookup.com/acer-aspire-e5-...#ffs-tabbed-14 and Acer’s bios setup “InsydeH20” has two boot modes: UEFI with Secure boot Enabled and Legacy.
    Which one is better suited for openSUSE?

    Both work as you might assume. Legacy because it is there for so many years and UEFI because it is around for a considerable time and thus used by many (without flooding the forums with problems).

    I made a mistake on the question.
    The question is :
    Which one is better suited for my laptop?

    Again, I assume both will work as both may be chosen from the BIOS.

    I am still a bit confused by your question. Things like KDE, network, etc. have nothing to do with this.

    Biggest consideration is if you dual boot or not. All OS's on a machine must boot using the same methods

    Hi
    If it's a newer system, I would guess the default is UEFI.

    So, UEFI requires the disk to be of type gpt, for Legacy booting the disk type requires to be of type dos.

    Both work with openSUSE, openSUSE works fine with secure boot on...

    Are you going to dual/multi boot the system?

    If your going to just run openSUSE or boot with Win(version?) then I would suggest UEFI.

    Boot from a live system at check the disk format....
    Code:
    lsblk
    fdisk -l /dev/sda

    ... also note that on some of the new laptops, their firmware might not be without problems.

    I have found on some that disabling UEFI in the BIOS and choosing Legacy did -- well -- nothing. The machine would still insist on booting EFI, so you literally really had on choice on those machines but to use UEFI.

    Thanks to sloppy manufacturers, UEFI can be poorly implemented so it becomes a pain in the butt!

    I would say, stick with UEFI, and make sure all operating systems you install are installed as UEFI. Some Acers are among the problem machines that refuse to respect their UEFI and Legacy BIOS switches.
